Aqara WS-K04E Smart Light Switch: Thread/Zigbee Protocol for compatibility with Apple Home, Google, Alexa, SmartThings, and Home Assistant
This smart light switch is for the homeowner who wants to upgrade their living room or kitchen lighting without rewiring. It gives you control over three wired circuits and one wireless button, perfect for setting up a morning scene that turns on lights and starts your coffee maker with one tap.
Think of it as your home's command center, not just a switch. The decoupled mode lets you use the top buttons to trigger automations, like turning off all lights when you say goodnight to your kids, without cutting power to essential devices. With Thread and Zigbee support, it connects reliably to Apple Home, Google, Alexa, and Matter, so you can manage everything from your phone. The power-off memory means your settings survive a brief outage, so you won't fumble for a switch in the dark. Install it with neutral or no-neutral wiring, and customize LED indicators in the Aqara app for a seamless fit into your smart home.
